Ascella

Quandela announces the launch of Ascella, the first functionnal Photonic Quantum computer. This is a key milestone for Quandela.

Ascella is a quantum computer that uses a highly efficient quantum dot single photon source, which functions much like a miniature box that produces single photons on-demand which then go into its universal interferometer to perform the computation and subsequently are detected at the output for processing.

At its core, Ascella is a unique piece of technology that uses light to perform complex calculations. Its hardware is made up of several key components. Firstly, there is the single-photon source which produces the photons on demand. This source emits photons into a fiber which then sends the photons on their journey through the system. The system contains a device called a demultiplexer, which is responsible for splitting the stream of photons into separate streams. So it feeds the chip 6 photons that arrive at the same time. Secondly there is the unitary matrix in the universal interferometer which determines the evolution of the photons and finally detectors (SNSPD) at the outputs.

Ascella is available in the cloud to more than 1,200 researchers and partner companies in 30 countries.
